[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 , an embodiment provided by the utility model:

[0019] A film compacting mechanism for contact lenses comprises a base 1 and a linkage rod 9, wherein a support rod 2 is fixedly connected to the top of the base 1, a limiting cylinder 3 is fixedly connected to the support rod 2, a concave pressure rod 4 is slidably connected inside the limiting cylinder 3, a connecting rod 5 is fixedly connected to the front side of the concave pressure rod 4, and a handle 6 is fixedly connected to the front side of the connecting rod 5.

[0020] Furthermore, the base 1 supports the mechanism to maintain the stability of the overall structure of the mechanism, and the placement groove 101 serves to place the linkage rod 9.

[0021] Furthermore, the support rod 2 is fixedly connected to the limiting cylinder 3 to maintain the stability of the limiting cylinder 3, and the limiting cylinder 3 is slidably connected to the concave pressure rod 4 to maintain the verticality of the concave pressure rod 4 when it moves up and down.

[0022] Furthermore, the limiting groove 301 limits the moving track of the connecting rod 5, and the supporting groove 30101 can support the connecting rod 5, and the connecting rod 5 is fixedly connected to the concave pressure rod 4, thereby preventing the concave pressure rod 4 from naturally sagging due to gravity.

[0023] Furthermore, the handle 6 is fixedly connected to the connecting rod 5, so that when the user pushes the handle 6, the connecting rod 5 and the concave pressure rod 4 can be driven to move synchronously. The concave pressure rod 4 is matched with the compacting seat 8, so that when the concave pressure rod 4 moves downward, it can squeeze the contact lens film with the compacting seat 8.

[0024] Furthermore, the fixing block 7 is fixedly connected to the compacting seat 8 to maintain the stability of the compacting seat 8 .

[0025] Furthermore, the linkage rod 9 is matched with the groove 601 on the handle 6 , so that when the user places the linkage rod 9 on the grooves 601 of multiple handles 6 , multiple contact lens films can be compacted simultaneously by pressing down the linkage rod 9 .

[0026] Working principle: place the contact lens film on the compacting seat 8, and push the handle 6 downward to drive the concave pressure rod 4 and the compacting seat 8 to squeeze the contact lens film and compact the contact lens film. When compacting multiple contact lens films, take out the linkage rod 9 from the placement groove 101 and place it in the grooves 601 of multiple handles 6, press the linkage rod 9 downward, and compact multiple contact lens films at the same time, with low cost, solving the problems raised in the background technology.
